This is probably the BEST orange liqueur available. It is far smoother than Triple Sec, more complex than Cointreau, and richer than Grand Marnier, with a more natural orange essence than all three.
Royale Montaine is the best bargain on the planet in the quality orange liqueur/cognac department. It's not as heavy as Grand Mariner, but it still makes an excellent topper for a margarita equal to Cointreau at a fraction of the price. It's almost impossible to find in the store, and the prices here if you buy a case with free freight are incomparable!
Of the several orange infused cognac's on the market I find Royale Montaine to be the smoothest and least harsh of all those I have sampled. Excellent balance of fruit and alcohol with neither overpowering the other. Delightfully drinkable!
The production process of fruit-flavored liqueurs can be relatively simple. Blending is the most common and most economic production method; flavoring, coloring, sugar plus any additional ingredients, such as preservatives and stabilizers, are blended with a neutral spirit to achieve a basic fruit-flavored liqueur.
